Wall mounting

Wall mounting 1/4

There are two types of mounting brackets available for the Husqvarna WS 400 series. One, the standard wall mounting to the right, which is supplied on delivery, and secondly the universal swivel mounting brackets to the left.

Wall mounting 2/4

Use the universal mounting brackets when cutting doors, cutting flush, cutting at angles and stair cutting as well as groove cutting. If you only require an everyday straight cut you use the fixed mounting. Fit the universal mounting brackets for the required cutting method.Note Find more information in the Tips section.

Wall mounting 3/4

Fit the standard mounting brackets as set out below:

Mark off the cutting line and mark off the expander bolts holes 165 mm from the cutting line.

Drill 15 mm holes for the M12 expander bolts.

Hang the mounting brackets loosely from the expander bolts, using M6S 12 x 70 or similar.

Wall mounting 4/4

Adjust the distance between the cutting line and the mounting brackets. The distance between the edge and the inner face of the saw cut should be 89 mm. Tighten the expander bolts.

Place the rail in the mounting brackets and tighten the compression washers.

Check that the rail sits correctly in the slots in the mounting brackets.

Connect Power Pack

Connecting Power Pack 1/4

Connect the incoming power cable (400 V, 63 A or 400 V, 32 A).

Connect the incoming water hose to the water coupling on the bottom of the motor front on the hydraulic unit.

Connect the remote control using the supplied Canbus cable. Tighten the cable connector screws by hand. When the machine is equipped with a radio, a radio antenna can be connected instead of a Canbus cable. This is screwed into the same socket as where the Canbus cable should have been fitted.

Connecting Power Pack 2/4

Check that the emergency stop switches on the power pack and the remote control have not been actuated by turning them in the direction of the arrow.

The display now shows “SELECT FUSE 63A”. If the available fuse is 63 A, confirm this by pressing the membrane key marked “OK”.

Connecting Power Pack 3/4

There are two types of hydraulic hoses for the saw: The four thin hoses control the feed motors, i.e. the saw's travel feed on the rail and the feed - removal of the blade. The two thick hoses drive the blade. The couplings should be wiped clean to reduce the risk of leakage before the hoses are fitted. Both the thin and thick hoses are locked by turning the outer sleeve on the female coupling so that the groove in the sleeve moves away from the ball.

Connecting Power Pack 4/4

Connect the hydraulic hoses on the saw in the same way as on the power pack.

Connect the water hose to the water coupling on the saw unit.

Confirm that hoses are connected correctly.

The hydraulic output must be set according to which machine is connected to the hydraulic unit. Select one of the following:

• 25 kW, 230 bar, 65 l/min

• 15 kW, 210 bar, 45 l/min or

• 9 kW, 140 bar, 40 l/min

Press OK to confirm the selection.

The display now shows “Husqvarna PP 455E START MOTOR”.

Assembling the saw

Assembling the saw

Fit the saw body in the saw carriage by lifting the saw body into position. When the saw is lifted into position, the locking handle moves into an intermediate position. In this position the saw remains in the saw carriage without it needing to be held. However, it is not sufficiently secured to begin cutting. To secure the saw, lift the locking handle towards the saw until the handle locks in position.Note With a vertical cut it is usually simpler to assemble the saw in the saw carriage with the handle upwards on the rail. WARNING! To cut without the saw securely assembled in the saw carriage and rail is associated with mortal danger.

Fit the blade

Fit the blade 1/2

Start by removing any dirt from the contact surfaces on the blade flange and blade.Check the blade's direction of rotation. The blade should rotate clockwise seen from the saw side and the released part of the diamond should lie in the blade's direction of rotation.

Fit the blade 2/2

Make sure the blade flange hub is fitted correctly on the cutting arm.

Hang the blade on the blade flange hub fitted on the cutting arm.

Mount the thrust washer on the blade by using the supplied 18-spanner to tighten the bolt until it is properly secured (tightening torque 30-40 Nm). Note Find other ways how to fit the blade using the blade flange hub in the “Tips” section under “flush cutting” WARNING! Exercise care when assembling the blade so that it does not risk becoming loose when cutting.

Fit the blade guard

Fit the blade guard

Lift the blade guard over the blade and hang the guard in the blade guard holder on the saw. Exercise care so that the runners on the blade guard are positioned in the slots on the water block.

Lock the blade guard by pulling the handle out from the guard. When the guard needs to be removed, press the handle in towards the guard.

Before cutting

Before cutting

Enclose the area to be cut so that unauthorised persons can not be injured or disturb the operator. Check that the blade guard is not damaged or broken. A broken or damaged blade guard must never be used. If cutting is to begin in another position than where the saw unit is located, run the saw unit to the start position. WARNING! A higher speed than the recommended speed can result in personal injury and damage to the equipment.

Cutting

Cutting 1/2

Always start by cutting a pilot cut. This is done by feeding the blade 3-7 cm. Now make the pilot cut. The cut should not be made at maximum speed, but with care in order to obtain a straight cut and with that a basis for the next cut.

Cutting 2/2

When the pilot cut is finished, a deeper cut can be made. The depth of these is determined from instance to instance and depends on factors such as hardness of the concrete, existence of reinforcing bar, etc. As the rail is symmetrical, the saw unit can be turned to make a new cut on the other side of the rail. The c-c measurement will then be 328 mm. In this way a cut piece is obtained that is in an easily handled size, making it easier to remove from the workplace. Note When the saw is turned on the rail, the water jet will be positioned away from the blade and will spray in the opposite direction, possibly up towards the ceiling.

Stop cutting

Stop cutting

Once cutting is completed, remove the blade from the wall and shut down the blade rotation and the water flow. Shut down the hydraulic unit.

Cleaning

Cleaning

The saw should be cleaned once cutting is finished. It is important to clean all the saw equipment. It is a good idea to disconnect the water hose from the pivot arm and use this to wash down the saw unit, rail, blade guard, wall mounting. If necessary you can also use a dish-brush or the like to clean the equipment. Do not use a high pressure washer to clean the saw.

Maintenance

Maintenance

In addition to the daily maintenance such as cleaning and lubrication, the machine must be serviced. When it is time for a service the text “time for service” is shown on the display on the remote control. After 50 hours of cutting, the machine should be serviced at an accredited Husqvarna workshop. The saw should then be serviced after every 100 hours of operation. The service is important so that as the user you have a machine that works as effectively as possible for a long time.

Mounting brackets

Mounting brackets

The mounting bracket is designed to be used when sawing chamfered surfaces, angle sawing, stair sawing etc. The brackets have two joints to make mounting easier on any wanted surfaces. The adjustment spline makes it easier to place the rail in the right position. Due to the pivoted construction a radial attachment of the blade is not necessary since it’s possible to angle the rail with the saw mounted.

Operation

Operation

Fit the mounting brackets, rail, and saw unit according to separate manual.

Start by sawing a vertical cut on the left or right side.

When each cut is finished, the complete unit is turned to fit next cut.

In this application the saw unit is turned anti-clockwise.

Finish by cutting the upper horizontal cut.

Remove the concrete block. Note It is very important to begin to saw a vertical cut and then continue with the lower horizontal cut. Using this method the last cut will be the top horizontal cut, which minimize the risk for the saw to get stuck under the concrete block.
